Neuroscientist Iain McGilchrist: Everything you’ve been told about the brain’s hemispheres is ‘almost the inverse of the truth’


Everything you think you know about the function of the human brain is wrong — and Dr. Iain McGilchrist, author of "The Master and His Emissary," is sitting down with BlazeTV host Auron MacIntyre to explain why.

According to McGilchrist, the modern belief that the left hemisphere is “verbal and rational and dependable” while the right hemisphere is “air fairy,” “emotional,” and “not very dependable” is a farce.

“All of that is completely wrong. In fact, it’s almost the inverse of the truth,” he tells MacIntyre on “The Auron MacIntyre Show.” “The right hemisphere, as I will explain, is far more dependable, far more stable, and the left hemisphere is prone to emotional outbursts of a very narcissistic kind.”


“It is prone actually to anger and to disgust and self-righteousness and emotions of that kind,” he explains.

And because of how important the brain is to each and every living being, the science surrounding it deserves to be challenged — which is exactly what McGilchrist is doing.

“In the left hemisphere, you see things that you already know what they are and you know you want to get them. They’re fixed, they’re isolated, they’re in a way fragmentary, they’re decontextualized, and they’re examples of a kind,” McGilchrist tells MacIntyre.

“Meanwhile, the right hemisphere is seeing a completely different world. It’s seeing a world in which nothing is ever fully certain," he says, adding, "It always might be something different."

Fibis I am just an average American. My teen years were in the late 70s and I participated in all that that decade offered. Started working young, too young. Then I joined the Army before I graduated High School. I spent 25 years in, mostly in Infantry units. Since then I've worked in information technology positions all at small family owned companies. At this rate I'll never be a tech millionaire. When I was young I rode horses as much as I could. I do believe I should have been a cowboy. I'm getting in the saddle again by taking riding lessons and see where it goes.
